The means of transport

Nowadays, there are several means of transport, for example, taxis, busses, cars, trains, planes… and all of them have advantages and disadvantages.
Taxis are very comfortable but they are very expensive. Busses are slower but there are cheaper, but they are always crowed. Trains are possibly the most utilized. By the way today the AVE is inaugurated. It was a train very loved and finally has down the traject Madrid – Barcelona and Barcelona – Madrid several times.
Today’s comments are that it’s very fast but it’s too expensive.
In conclusion, I think that the means of transport, in general, are good, because they don’t polluted to mach.
For these reasons, I prefer the public transport to the private car.
